Methamphetamine Identification in Four Forensic Cases

Specimens that tested positive for amphetamines by immunoassay were confirmed by mass spectrometry. The absence of detectable d-amphetamine (limit of detection at 50 ng/mL) with a positive methamphetamine prompted further testing by chiral derivatization. This data demonstrates that d-amphetamine need not be present in methamphetamine positive cases.
